Classic porcelain gets an update with the double wall construction of the Bodum® Canteen 2-piece Large Glass Set! Although you will enjoy admiring the fun, uplifting design of these glasses, it’s the functional features that will quickly make them your daily cup of choice. The double wall design enhances the thermal properties, keeping the temperature of hot beverages hot for a longer period of time while remaining cool to the touch. They will also keep cold contents chilled longer. And because it’s crafted of borosilicate, these glasses are stronger than traditional “soda-lime” glass.
